In IPv4 the default route can be written as 0.0.0.0/0 In IPv6 the default route can be written as ::/0 If u try owipcalc 0.0.0.0/0 contains 1.1.1.1 or owipcalc ::/0 contains ::1 owipcalc will respond with 0 meaning that the "default prefixes" do not contain the routes. That is why we check now for 0 prefix. Furthermore, if the prefix is 0, i will be 16. We will access a negative array entry in the line: uint8_t net1 = x->s6_addr[15-i] & m; Divide by % 16 to prevent i becoming 16: uint8_t i = ((128 - a->prefix) / 8) % 16; Signed-off-by: Nick Hainke <vincent@systemli.org> |
